tain new and useful Improvements in Harvesting-Machines; and I do hereby declare that the following is a full and/exact description thereof, reference being had to the accompanying drawings and, the letters of reference innrltr-l thereon.

Figure I is a plan xiiew." Figll is a side elevation. Fig. III is an elevation' of the pivotal shoe and the rear end of themain frame. FiglV is a cross-section of the finger-bar and elevation of guard-finger.

Letters of l e name and kind refer tolike. parts in each' f the iigures.

, A is the linger-bar. This is made of metal (I prefer boiler-iron) in the concave-.convex form. The-guards brest upontheupperorconcave side of the bar, and are secured thereto by means of screw-bolts@ passing through the bar and guardsj-The cutter-bar dis supported upon the 'guards and over thetinger-har; but I contemplate'making the guards of sulicient length A to support andusethe cutters in front of thenger-bar. This form of finger-bar comn bine'sstrength with lightness of metal, and also gives a runner form in backing, as Well as when moving forward.

E is a pivotal shoe. This I make of cast-iron. Its 'bottom4 part is made convex, and about seven inches of its inner end lits the yconcavityv of the linger-bar, and is bolted thereto, as shown at r2, Fig. III. The upright part of the shoe 1s connected to the rear end ofthe frame by means of a strong-bolt, as shownatf, Fig. III. It moves freely on this bolt, soas to a1- low the finger-bar to conform to the unevenness ofy the ground or to be raised therefrom,

I asmay be required. It has abroad bearing upon the end piece of the frame Z2, so that the bolt'f will holdyit in,v place and resist any lateral strain. It also has length outwardly from the'r bolt j', so as to give sufficient leverpurchase, through the action of compound levers g h z', to raise the linger-bar from. the? ground. h lies parallel with the frame, and is connected `thereto by m ns of two journalor pivotal center, the iinger-bar is thereby raised from the ground quickly and easily and at any time it may be desirable to do so.

J is the multiplying-wheel. o 'lliis'isl placed at the rear end of the machine and in line with u the cutter-bar.

-K is' acrank-wheel. This is supported in a sliding journal-box, L, -Ifig. II. A'ilange, L2, .is-projected from the upper end of this journal-box.` The end of the lever M- catches onto this ange. The lever M is pivoted to a small standard, as shown atm. The standard m3 has notches 'which hold the lever M'where placed.

By a slight movement of the lever M the crankrwheel may be thrown in or out of gearA with the multiplying-Wheel at pleasure. l

Nis a tripping-arm made fast to the pro-y jecting axle ofthe driving-wheel.

OV is a lever pivoted to a standard onthe.

frame, as shown at I).

. Q is arake jointed to the levert), as shown at G2,

It is a lever jointed in the'middle and connected to the rake by a joint, as shown at R2, and Vconnected to'the crank, as shown at R3.

S is a crank-shaft supported by the arm w, and has ahearin'g in the journal-box of the driving-Wheel"shaft,`

'I is a pinion oikthe `shaft This pinionmeshes in with acog-rim supported on the arms ofthe driving-wheel.

Als the machine moves forward the trippingarm N `Will strike thelever 0 and bear it down at the proper time to raise the rake and carry it cover the grain (lying and falling on the platformlto a position parallel withthe cutters, at which'pointthe trippingla'rm slides olii' from the lever O and the rake Q falls down upon the grain which has accumulated upon the platform. The arrangement oit' the gear is such as to cause the rake to sweep the grain fromthe platform after the tri )ping-arm has passed off from the lever and strikesthe lever, and so that the trippingarm Will strike the lever and raise the rake while x the rake is being carried back to its pa/rallel position over the platform. p f
